Mate (fig. 119).—Alar expanse 20-24 mm. Frons conical. An- 
tenna ciliate, cilia about one-half as long as width of shaft. Midtibia 
incrassate, hair-pencil well developed. Outer spur one-third as long 
as inner. Similar to marculenta in color and maculation, but speci- 
mens of mancalis are somewhat duller and less ochreous, with defi- 
nition of markings sharper, subterminal band of forewing usually 
broader anteriorly, and subterminal line of hindwing closer to outer 
margin (pale ochreous area between line and outer margin of wing 
narrower than subterminal line). 
Genitalia (fig. 27): Harpe without digitate setae; with two con- 
spicuous subequal hooklike structures; the small one downcurved, 
arising from near middle of harpe and extending below ventral margin; 
the large one from sacculus, rather broad basally, distal termination a 
sharp point; pad moderately broad, rounded, scobinate. Aedeagus 
somewhat attenuate distally, bluntly pointed and with a patch of 
small spinules. 
Frmate.—Alar expanse 22-24 mm. Similar to male in color and 
maculation. Genitalia (fig. 89): ductus bursae rather strongly 
sclerotized from ostium to junction with ductus seminalis and some- 
what incrassate near middle; ostium with lateral production short, 
spurlike. 
Larva.—Mature, 28-30 mm long. Head pale amber, reticulation 
weak. Body color sordid white. Pigmentation of markings on 
prothoracic shield and body pinacula brown or blackish. Prothoracic 
shield with pigmentation restricted to lateral margin. Pinacula of 
seta Ia-Ib and IJa-IIb of meso- and metathorax moderately convex, 
irregularly ovoid or round in shape, pigmentation strong. On ab- 
dominal segements 1-8: Pinacula of seta I and seta II conspicuously 
large, round and flat; pinaculum of seta III reniform and smaller than 
those of setae I and II; pigmentation of setae I, II, and III strong; 
pinacula of setae below level of spiracles not pigmented or the pig- 
mentation obsolescent centrally. Ninth abdominal segment with 
pinacula not pigmented.
